Compiling on Linux

my apologies for cross-posting but I wasn't getting any response in Inkscape-User so I thought I might have posted to the wrong list. I tried to install the latest autopackage of Inkscape but it seems my glibc is too old (Requires GLIBC_2.4 - I have GLIBC_2.3.6 ... is it possible to release a GLIBC_2.3.6 autopackage?) and the package suggested I install from sources. When I try to compile the source, i get an error - ui/dialog/ocaldialogs.h:247: error: expected class-name before '{' token ui/dialog/ocaldialogs.h: In constructor 'Inkscape::UI::Dialog::FileListViewText::FileListViewText(guint, Inkscape::UI::Dialog::SVGPreview&, Gtk::Label&, Gtk::Button&)': ui/dialog/ocaldialogs.h:250: error: class 'Inkscape::UI::Dialog::FileListViewText' does not have any field named 'ListViewText' I use Debian Etch (stable) so it seems compiling myself is my best option but I have tried with about 5 different source packages and the result is always the same (the package which created this error was 16060 but it is still there in 16148).

Failing compile with 2geom/path.h
by Mason Thomas 14 Nov '07

14 Nov '07

Hi, I have recently been unable to compile Inkscape on Linux because of a compile failure in nodepath.cpp. It exhibits the same failure, even when I checkout an older version that used to compile for me! Here is the beginning of the message I get (it goes on much longer), could someone please help? Thanks, -Mason In file included from live_effects/effect.h:16, from live_effects/lpeobject.h:13, from nodepath.cpp:50: ./2geom/path.h:72: warning: `virtual Geom::Curve* Geom::Curve::reverse() const' was hidden ./2geom/path.h:313: warning: by `Geom::Curve* Geom::SVGEllipticalArc::reverse(double, double) const' ./2geom/path.h: In member function `Geom::BaseIterator<__gnu_cxx::__normal_iterator<Geom::Curve**, std::vector<Geom::Curve*, std::allocator<Geom::Curve*> > > > Geom::Path::begin()': ./2geom/path.h:376: error: `Geom::BaseIterator<IteratorImpl>::BaseIterator(const IteratorImpl&) [with IteratorImpl = __gnu_cxx::__normal_iterator<Geom::Curve**, std::vector<Geom::Curve*, std::allocator<Geom::Curve*> > >]' is private ./2geom/path.h:472: error: within this context ./2geom/path.h: In member function `Geom::BaseIterator<__gnu_cxx::__normal_iterator<Geom::Curve**, std::vector<Geom::Curve*, std::allocator<Geom::Curve*> > > > Geom::Path::end()': ./2geom/path.h:376: error: `Geom::BaseIterator<IteratorImpl>::BaseIterator(const IteratorImpl&) [with IteratorImpl = __gnu_cxx::__normal_iterator<Geom::Curve**, std::vector<Geom::Curve*, std::allocator<Geom::Curve*> > >]' is private ./2geom/path.h:473: error: within this context

Using multi-path objects with the "Pattern along path" or "path along path" effects
by Tony Vigil 14 Nov '07

14 Nov '07

Currently, only a single path can be placed along the path in a single instance of the effect. Will either effect ever be able to place an object (with multiple paths) along a path? Perhaps even turned into a stroke style??? The reason I ask is that it would be very nice to be able to create brushes (objects with multiple paths) that could be placed along a path. Here is an example of what I am talking about... http://soundnvision.homestead.com/files/brush_along_path.png The steps required to make the various shades of my example brush follow a single path is very time consuming. After I trace the bitmap, I need to include a bounding rectangle with each object that makes up the different shades of the brush so that each element is placed relative to all other elements along the same path. Then, each element is placed along the path separately. You can't edit the original path and have ALL of the elements respond accordingly. Therefore, you must start the process all over again if you don't have the original path placed exactly as as you need based on your brush shape. Best case scenario... this effect becomes a stroke style that can be applied to any object (i.e. rectangles, ellipses, text, spirals, etc.), not just path objects. The only other place I've ever seen this type of tool is in Microsoft Expression. Inkscape's path effect comes close, but doesn't quite hit the mark. - Tony

student project : distortion envelope tool
by Steren Giannini 13 Nov '07

13 Nov '07

Hello, It is now official for the administration of our school, we are starting working on the "distortion envelope tool" at the end of december. Our official "tutor" from the dev team is Johan Engelen. The school is only interested in observing how we manage to organize our project alone and if we meet the requirements. I'll be the project leader, we are 6 in the team and we will be working for 5 months. (from 4 to 8 hours a week) We are before all inkscape users and we are very exited to build something for it. The goals are : - create the distortion tool engine for paths (using lib2geom, and path effects) - create the tool's UI - extend path effects to groups for the distortion tool and others (path along path for example) Of course : - SVG compliant - The original object is saved. If the project goes well, the goals could be extended. We'll see with Johan. (nb : Yesterday, I was thinking about path effect on clones, path effect on texts...) Bye, Steren

Will it require any changes in the existing extensions? I think it should be done before 0.46 then, because it will make a lot of different extensions easier, and the API changes should be done as early as possible. -- bulia byak Inkscape.

dirty on load
by bulia byak 13 Nov '07

13 Nov '07

This is one of the most annoying and visible recent bugs - right after clean start, the empty document is dirtied and it asks if I want to save it upon quitting. The undo stack is empty however. Can anyone please look into it? I think it's pretty recent. -- bulia byak Inkscape. Draw Freely. http://www.inkscape.org

Inkscape profiling: Inkscape::FontLister::FontLister question
by John Bintz 10 Nov '07

10 Nov '07

Hi, all. I'm experimenting with profiling Inkscape in Valgrind looking for potential slow spots in the code, and had a question for those with more knowledge of the font loading code. One of the first places in the initialization code where I think there could be a speedup is in Inkscape::FontLister::FontLister. This method calls font_factory::Styles once for each font family that is returned by font_factory::Families. In my test run of opening and closing Inkscape with 142 font families returned by font_factory::Families, running Inkscape::FontLister::FontLister took just over 20% of the total runtime. If there were some way to cache this font information between runs of Inkscape and only update it if the fonts on the system have changed, or if there was a way to push back the loading of fonts to later in the program execution -- say the first time someone viewed the Text toolbar or something similar -- I think it might speed up startup time in Inkscape. Anyone willing to help me take a look into this to see if this will work? Thanks, John

Fix for Font Name Case bug #1818885
by Thomas Worthington 09 Nov '07

09 Nov '07

I've put a diff that fixes this bug at http://www.tww.cx/downloads/fontcase.diff I'd love to say that there must be an easier way but instead I'd like to say that the person that defined the C++ string class without case-changing functions should themselves be strung up! The method used needs to be checked by someone who actually knows C++ to see if it will handle non-ASCII font names. I don't have any such fonts to test it with and I'm not sure enough about how C++'s toupper function works on unicode to even guess whether it will work or not. The diff file also adds some comments to toolbox.cpp. Thanks to Gail for pointing me in the direction of that file, BTW, it would have taken me even longer to come up with a fix without her quick reply to my query. Finally, the diff file has some changes to a pair of makefiles which are a mystery to me; I never touched them, Gov'nor! Thomas
